Question

How do you simplify `(-2)0 - (-2)1`?

Answer 1

The answer would be 2. See steps in explanation.

Explanation:

We can break down this expression using the order of operation, or " PEMDAS ".

P - Parentheses
E - Exponents
M - Multiplication (can switch spots with division based on order from left to right)
D - Division
A - Addition (can switch spots with subtraction based on order from left to right)
S - Subtraction

`(-2)0 - (-2)1`

`-2 * 0 - (-2)1` Let's multiply first, since it's the first operation in PEMDAS we can do first.

`0 - (-2)1` We got `0` from the first step. We see a subtraction sign, but there is also multiplication, and we need to do multiplication first.

`0 - (-2)` We multiplied again, and now we're left with one thing left to do, subtract. Notice we are subtraction a negative, so we must add.

`0 + 2` This part is simple

`2`

**Our final answer is `2`.
